OMG Word Professor

Letters sit on a small board and you connect them by tapping or dragging your finger, building a word one letter at a time. There's no fixed path — any adjacent letter counts — so the same set of tiles can hide several different answers if you look long enough. Short three-letter finds get you moving, but the game keeps pushing you toward longer combinations as you go. It's the kind of word puzzle you can pick up for two minutes or stay with for twenty.
